The old town hall of Bamberg was built in 1386 in the middle of the Regnitz River, accessible by two bridges. According to legend the bishop of Bamberg did not grant the citizens any land for the construction of a town hall. This prompted the townsfolk to ram stakes into the river Regnitz to create an artificial island, on which they built the town hall they so badly wanted.
The Old Town Hall's frescoes never fail to impress as they lend the facades a three-dimensional quality achieved with trompe d'oeil architecture. A special detail is a continual source of mirth among tourists: the leg of a cherub protudes out of the wall as a sculpture. Today the Old Town Hall accommodates the prestigious rococo hall and the Ludwig Collection.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
